Title: Determination of yeast activity
Inventor: IMAI TAKEO
IPC: C12N1/18
Filed: 1991-09-26
Abstract: PURPOSE:To easily, simply and accurately determine yeast activity such as proliferativity or fermentativity in a short time by leaving yeast to stand in a low-pH environment followed by measuring the pH value in the cells. CONSTITUTION:Firstly, yeast is left to stand in a low-pH (<=6, pref. 2-3) environment for a specified time (pref. 30-100min). Thence, the pH value in the yeast cells is measured, for example, by such a means that 5,5-dimethyl-2,4- oxazolidinedione (DMO) is added to a suspension of the above cells followed by equilibration, and the DMO concentrations in both the inside and outside of the cells are determined; from the resultant partition degree, the pH value in the cells is calculated. Based on the results, yeast with higher pH value is determined as more active than that with lower pH value. For realizing the low-pH environment, it is recommended that an inorganic or organic acid be added to an aqueous suspension of the yeast.

Title: Thermal recording material
Inventor: SUZUKI HIDEYUKI
IPC: B41M5/30
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To improve blocking resistance to a protective layer surface while an adhesiveness to a remoistening size layer is excellent by a method wherein a Bekk smoothness on the remoistening size layer containing a remoistening size is specified. SOLUTION: A Bekk smoothness on a remoistening size layer surface is made to have 50 to 1000 sec. In the case of under 50 sec in the Bekk smoothness, when an amount of water in remoistening is little, adhesiveness of the remoistening size layer may remarkably be decreased. Further, in the case of over 1000 sec, when a thermal recording material is finished in a coiled state, the remoistening size layer surface may be stuck to a protective layer surface (blocking). For a method in which the Bekk smoothness is made 50 to 1000 sec, it is preferable that two or more kinds of remoistening sizes which are incompatible with each other are jointly used, or a pigment is added. Then, as the rehumidifying size, joint use of polyvinyl alcohol and a starch derivative such as starch or oxidized starch, esterified starch, etc., is preferable because of excellent blocking resistance.

Oscillation with rectangular wave is generated from an oscillation signal generating circuit 26 having output level of the integration signal centered, the output from the comparator 20 through a proportional amplifying circuit 23 is added the rate, and based on this, feedback compensation is added. It is thus possible to maintain high exhaust gas purifying efficiency in a wide control range.
